Resources and Going Further

Understanding how hexadecimal works is key to so many areas of electronics and programming.

Armed with your shiny, new hex knowledge, here are some related tutorials you may want to check out from here:

  • Digital Logic and Shift registers -- These tutorials use hex as a foundation for larger, more general electronics concepts. Digital logic is the core behind all of the decision making a computer does. Shift registers can be used to fan a single input or output out to 8-or-more.
  • I2C and SPI -- These communication interfaces almost always require use of hex in some way or another. Devices that communicate of SPI or I2C usually have a list of registers, which are all mapped with hexadecimal addresses. I2C devices are all assigned unique, 7-bit addresses, which are usually presented in hexadecimal.

Binary Blaster

  • Binary Blaster Hookup Guide -- If you're looking to practice your hex conversions, the Binary Blaster Kit can be a great help. This is a soldering kit. Once you've put it together, use it to test your knowledge of how binary, hex, and decimal are related.
